Fix Precision 7760 (rtx4000, i7) fan goes loud, runs very hot while closed, sudden black screen, randomly showing 0% and hangs
Hi everyone,
As the title says, I’ve been trying to fix this issue since the day I bought the laptop. The problem eventually destroyed the original battery, thankfully the warranty covered the replacement, but every diagnostic test showed no hardware faults.
The issue usually happened when the battery was above 80% and the laptop was still connected to the charger. I tried every fix I could find online. My suspicion was that during charging, the system was switching between battery power, charger power, and the integrated GPU, which caused instability.
I finally found a solution (well… sort of). These two steps completely stopped the random shutdowns and overheating for me:
1- Enabled Hibernate and set the power button to trigger Hibernate.
2- Disabled the integrated GPU in BIOS, leaving only the RTX 4000 active.
(Device Manager now shows only one GPU.)
And just like that, no more weird incidents. As a bonus, SolidWorks runs noticeably better now.
I spent way too much time figuring this out, so I’m posting the fix to help anyone else dealing with it.

Hi Tesla1856,
Thanks for the reply.
I already tried increasing the fan speed/cooling, but it didn’t help. The overheating is severe: the fans ramp to full throttle and then the system shuts down. When that happens, the only way to stop the overheating quickly is to unplug the power adapter, but that only stops it temporarily as the problem returns as soon as I reconnect the adapter, especially when the battery is above ~80%.
This became so annoying that I disabled the discrete GPU, and since then the issue has not returned. The tradeoff is that the fans now run at a mild level all the time and battery life is a bit lower than before. Still, it works fine as a workstation since I’m on the power adapter most of the time, and ~3 hours of battery are sufficient for my use.
-I already tried many ways to reduce heat, nothing worked.
-I turned HAGS to always ON, no problems yet. (I also set the GPU dedicated to graphic tasks)
-Already tried disabling VBS, didn't resolve my laptop problem.
Regarding The "Hibernate",
Sleep function was not fully sleeping while lid was closed so it turned hot and the fans ran and deplete the battery for no reason
I tried your solution and it worked (i.e. turning windows OFF before putting in my backpack and turning ON later).
Then I activated Hibernation capability of the windows 11 and set it to "activate when the lid is closed". Now I don't have the hot running laptop issue in my backpack anymore, and hibernation is more convenient. I just close the lid and go.
problem resolved.

Thanks for posting the work-around.
You might also want to try:
BIOS: Set Thermal Fan Curve to "More Fans for Cooler"
BIOS: leave both GPUs enabled
In Windows:
In Device Manager leave both GPUs enabled (leaving a "clean" DM).
Power-Profile to High-Performance
Turn off HAGS and set SolidWorks to High-Performance Nvidia GPU
Disable VBS (Core Isolation / Memory Integrity)
Don't use Hibernate or Sleep. Just turn-on, use it, shut-down when finished.
I have similar ... a XPS-15 (9520) with Intel-i7 , dedicated Nvidia GPU, 32gb, NVMe-SSD
